I was basically trying to demonstrate based on these conflicts that what we are seeing is what we are really like. We don't teach children to be bad. We teach them to be good. And the tricky part is teaching them WHY they should be good.
He simply didn't get it. He thought it was just innocent conflict. Innocent yes, because the kids don't know any better. But did he ever reflect on why he knows it's good to compromise and to share? Perhaps not, because he must have assumed that we eventually come to that realization simply by aging, I guess, since we are basically good.
